摘要
The paper implemened forest resources data updated by designing survey database of resource (including subcompartment database and tree species database) and database of resource(including changed database of subcompartment and changed database of tree species) change,compartementalized database of resource survey into two processes—stand growing naturally without interference and stand changing caused by the interference of environment.The data of natural forest resources was updated by applying interrelation between database and adopting different types of growth and management models respectively on the base of network database language—PowerBulider and Visual C as well.
